The Power Wah Volume is a combination vintage wah and an optical volume pedal with modern features. It's equipped with Morley's HQ2 inductor that was custom designed for authentic vintage tone but manufactured to today's highest standards. It also has electro-optical circuitry so there's no pots to wear out, and a "TrueTone" bypass ensures pure tone and maintains in bybass and Wah modes. It's built into a cold-rolled steel housing that'll take years of abuse. Other features include On/Off LED, easy-access battery compartment, and a two year warranty. Also great for bass!
